Patent DE-4110720-A1 (DE)
Title: Coupling between tool-holder and machine tool
IPC: B23B31/26
Filed: 1991-04-03
Abstract: The mechanism consists of a cylindical toolholder coupling piece (5) with a coaxial pin (23) which locate in the coupling body (3) and an integral draw bolt (37) respectively. Clamping is facilitated by bevel gear arrangement (35, 41) which causes the draw bolt (37) to be pulled, by means of a thread arrangement (40), so as to cause the cam mechanism (69) to act upon the angled faces (19, 71).     The clamping device (51) may have an eccentric cam offset from its axis (43) which locates in a recess in the drawbolt (37) and by rotating the clamping mechanism about its axis causes the drawbolt to be moved along the major axis (11).

Title: Break bolt with weakened shank for cable connector - has protrusion from neck into keyhole, limiting key entry until torque-limitation head is sheared off
Inventor: CZERNEK GEORG
IPC: F16B31/02
Filed: 1991-04-23
Abstract: A smaller head (12) is joined to a larger externally-threaded body (18) by a narrow neck (14) through which the bore (24) for a tightening tool of hexagonal cross-section extends down to the body (18). The tightening torque is limited by a circumferential groove (16) at which the head (12) and neck (14) are sheared off when the limit is exceeded. A protrusion (30) from a recess (28) into the bore (24) restricts insertion of the tool. ADVANTAGE - Esp. effective and highly reliable bolt is easily mfd. and its body can be unscrewed after the head has been sheared.

Title: Storage and/or transportation of nucleic acids in undissolved form - by binding acids reversibly to mineral solid, e.g. silica gel or glass
Inventor: HENCO KARSTEN DR
IPC: C12N15/10
Filed: 1991-06-14
Abstract: Storage and/or transportation of nucleic acids in undissolved form comprises binding the nucleic acids reversibly to mineral solids and storing and/or transporting them in the adsorbed state. Solid is (non)porous-silica gels and/or glasses. Particle size of the solid is 0.1-1000 microm. The solid is esp. in particle, plate, membrane, filler or rod form. Nucleic acids are pref. bound to the solid under conditions of high ionic strength and eluted from the solid under conditions of low ionic strength. In particular, the high ionic strength conditions are provided by 5m NaCl soln. (contg. other components, e.g. other buffer salts) and the low ionic strength conditions are provided by a soln. of NaCl (100 mM) (contg. other substances, e.g., other buffer salts). Adsorbed acids are pref. shipped or stored in solid form or as a suspension in organic solvent, esp. EtOH. USE/ADVANTAGE - Process allows storage and transport on nucleic acids with the acids losing their biological activity. Unlike previous processes, e.g. where the acids were stored in bacterial plasmids in a frozen state, it is not necessary to cool the adsorbed acids, and they are even stable up to ca. 70 deg.C. The process is cheap and technically easy.

If these are opened movement of the cage is immediately stopped. As a further safety measure the cage can be equipped with press button switches that must be held down by both hands of each occupant before the cage can be moved. ADVANTAGE - Greater safety during operations such as stock taking, or system assembly and repair.

Title: Thinly coated substrate forming T-shaped structure for testing characteristics of thin film material - has right-angled bend in each residual section of thin film supporting central limb of T
Inventor: ZHANG JUNMING DIPL ING
IPC: G01N3/00
Filed: 1991-10-18

The lateral portions (8,9) support the centre (10) flexibly but exert next to no influence on variations in its length which consequently give a very precise measure of internal stresses. In an alternative embodiment, two such T-structures are formed back-to-back and thinly coupled. USE/ADVANTAGE - E.g. for determining thermal expansion coefficients or breaking elongation. Max. variations of geometrical dimensions can be detected with greater accuracy in consequence of normal stresses.

Title: Electronic circuit testing for PCB mounted devices - reprogramming logic components for test function, stimulating circuit nodes for testing and reprogramming useful function
Inventor: ENGL BERNHARD
IPC: G06F11/267
Filed: 1991-11-06
Abstract: Reprogrammable logic components are programmed to carry out test functions for the circuit, and after the end of the test they are reprogrammed for the actual useful function. The programming may involve the formation of test function signal paths that would be too expensive to sensitise for useful functions, in order to stimulate circuit nodes for testing. Signal paths may be formed which are not present for the useful function or which would be two expensive to sensitise for the useful function, in order to allow observation of circuit nodes. ADVANTAGE - Number of adaptor pins is reduced (ideally to nought) without components requiring additional test cells or circuits.

Inventor: CHEHAB FIRDAUSIA DR
IPC: D02J1/18
Filed: 1992-03-25
Abstract: A tow is drawn from a bale and its normally interlaced fibers are separated from each other by applying to the fibers a positive or a negative electric charge so that the neighboring fibers repel each other, the separated fibers are contacted by particles of finely atomized plasticizer which carry electric charges of opposite polarity so that they are attracted to the separated fibers, such charging of the fibers and the application of plasticizer can take place prior or subsequent to at least partial conversion of the tow into a rod-like filler. Several tows can be treated simultaneously to thus enhance the output of the machine and/or to improve the quality of the products.
